PERMANENT WAY OF RAILWAYS OR TRAMWAYS.

SPECIFICATION forming part Of Letters Patent N0. 728,652, dated May 19, 1903.

Application filed September 18,1902. $erial N0. 123 ,926. (No model.)

To all whom it may concern: I

Be it known that I, ALEXANDRE AMBERT, engineer, a citizen of the French Republic, residing at 19 Quai Yayr, Lyons, France, have invented certain new and useful Improvements in the Permanent WVays of Railways or Tramways, of which the following is a specification.

This invention relates to the permanent ways of railways and tramways, and has for its object to increase the stability of such permanent way whatever may be the kind of railway or tramway and form of rails.

According to this invention the rails are secured in position by means of elastic supports and of elastic keys or wedges forced under great pressure between the rails and the said supports. The keys or wedges owing to their elasticity and that of the support cannot become loose, however great may be the shocks caused by the vehicles running thereon.

In order that my invention may be clearly understood, I will describe it with reference to the accompanying drawings, in which Figures 1 and 2 show in section and elevation my invention applied toa suspended railjoint of Vignole rail. Fig. 3 shows application to agrooved rail of the Broca type. Figs.

4: and 5 show in section and elevation an application to a Vignole rail for its connection to metallic sleepers. Fig. 6 is another construction of this application. Figs. 7 and 8 show another kind of connection. Figs. 9 and 10 show the invention applied to the connection of a rail with a metal sleeper by means of a cross-shaped block. Fig. 11 shows a rail connection with a metal sleeper by means of a hooping device.

In applying my invention to a suspended rail-joint, Figs. 1, 2, 3--that is, a joint between two rail ends between sleepersthe adjacent rail ends (1 cl are heldin a support or clamp a, of highly-elastic metal, having clips extending over the flanges of the rails, and between the under side of the said' flanges and the support elastic keys or wedges b c are driven with great force; The rail-flange may be secured by one key or wedge or many keys or wedges. The support a may be made in one or in two or more parts. If made in parts, each part is provided with upper and lower turned-in portions, between which the railflange is secured by a key or wedge or keys or wedges, as hereinbefore described. The said support may be strengthened by ribs. The driving in of the keys or wedges may be effected by a screw-jack, hydraulic pressure, or other suitable means. In order to obtain a more powerful'grip, the support may be heated before being placed in position. For connecting the rails to metal sleepers, Figs. 4, 5, 6, the support a embraces the rail d and the sleeper c, Fig. 6,0r embraces only the rail and is riveted to the sleeper, or it may be made integral with the sleeper, Figs. 4 and 5.

. In this case the support may be only a hook g, Figs. 7 and 8. The fasteningof the rail to the support is effected by driving akey or wedge or keys or wedges forcibly between the support and the under side of the rail-flange, as hereinbefore described with reference to the fastening at the suspended joint. The required canting of the rail can be obtained by giving a suitable incline to either the key or wedge or one of the keys or wedges or to the support or to the sleeper. In the application shown in Fig. 6 the canting is obtained with an inclined key b. In this arrangement the support a embraces the sleeper e and the rail 01. In the arrangement shown in Figs. 4 and 5 the canting is obtained by giving a suitable incline to the support a, riveted on the sleeper e.

Figs. 7 and 8 show an application with hooks g riveted on the sleeper, andFig. 9 with a cross-shaped block--that is to say, a block being grooved for embracing the rail and being grooved in a perpendicular direction for embracing the sleeper.

Fig. 11 shows a rail connected with a metal sleeper by means of a hooping device.

Having now particularly described and ascertained the nature of my invention and in what manner the same may be performed, what I claim is- In a rail-joint for railways the combination with the rails of an elastic clamparranged beneath the meeting ends of the rails and em- In testimony whereof I have hereunto set bracing the upper sides of the rail-flanges, and my hand in presence of two subscribing witan elastic key or wedge forced under great nesses. pressure between said clamps and the bottoms of the rails, said key or wedge being dis- Witnesses:
